To all whom it may concern:

Be it known that I, HARRY B. Wonrn, a citizen of the United States, and aresident of Oakland, county of Alameda, State of California, have invented a new anduseful Mop, of which the following is a specifica tion. My invention relates to a mop of the selfwringing type.

An'object of the invention is to provide a mop in which the compressibility of the cloth is utilized to provide the desired resiliency of the wringing pressure, thereby eliminating the use of springs.

Another object of my invention is to pro vide a mop of the self-wringing type .in which practically the full length and width of the mopping cloth can be used in .the mopping operation.

A further object is to nrovide a mop in which the length of cloth available for use in a mopping operation may be varied as desired, and which may be used as a scraper without changing the position of the 95 mounting of the mop cloth or adding an extra member. i

A still further object of my invention is to provide a mop of the character described in which a mopecloth of any desired material 30 or form may be inserted and used without diificulty. 7

My invention. possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in thefol- 35 'lowing description of the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the specification. It is to he understood that I. do not limit myself to the showing 4 made by the said drawingsand description,

as I may adopt such variations of the preferred form as fall within the scope of my invention as set-forth in the claims.

Referrin to said drawings:

Figure 1 is an end elevation of the mop in position for use, the stick or handle portion being broken away.

Figure 2 is a side view of the upper side of the mop as shown in Figure 1.

Figure 3 is a section of the mop taken on the line "3,-3- in Figure 2.

Figure 4 is anenlarged sectionof one. of, the'rolls of the device taken anthe line in Figure e Briefly eiipressed themop in its present embodiment f compr is es a frame supporting a pair of spacedparallel rolls around which passes a belt to whichone end-oi the mop cloth'is attachedi Apa-ir ot parallel-rollers y is carried on the frame, oneof the rollers being ositioned to cooperatewithone oi the fol s so that upon movement of: the belt the cloth will be passed between the roll and roller and the" water expressed therefrom, the other roller engaging the belt. in

such manner that pressure between the first mentioned roll and roller will be maintained. P The saidfirst roll' and roller are carried at the lowerend of the frame so as to allow a maximum amount of the cloth to be available for the mopping operation. Hand operated means fare provided for rotating the rolls. Means are "also included for holding the cloth in the' lmost effective position for use.

A detailed description follows:

The mop as here shown comprises a rectangular frame 2 to the upper oross member 3 of which is attached a suitable handle .4.

R otatably mounted adj acent the ends 3 and f 5 of the frame are rolls 7 and 8 which are disposed in parallel relation to the ends of the frame. i-Circum ferential beltgrooves'9 are provided in the rolls inlwhich an endless and relatively inelastic belt 11 is adapted to fit, the groove being of such depth that the outerf surface of 'therlielt'wil-llbe' flush with the surfaces of the rolls. Rotation of the roll? is-preferably effected by means of the crank 12 which fixed to the roll 7, the surface of groove 93 in roll 7 being provided withteeth 10 tohinsure a non-slipping engagement with the belt.

= "Suitably attached to belt 11 is a stirrup 14: in which a mop cloth 13 is adapted to be ,held, said stirrup comprising flexible side members l l and a relatively stiff cross-memher 15, and is secured on the outerside of v the belt for movement therewith.

Pressure means are provided whichare adapted to cmoperate with the-roll 8' for wringing-the cloth upon appropriate .moyement of the belt. As here shown, similar levers 16 are oppositely pivoted in the sides of frame 2, and rollers 17 and 18 are rotatably mounted in parallel relation on and between the corresponding ends of the levers. The pivoting of the levers 16 is so positioned that the roller 18 is normally in contact with the roll 8. Thebelt 11, being disposed about the members 8, 7, and'17, is of such length that it will be caused to tighten as roll 8 and roller 18 are caused to separate, thus resisting the separation of roll 8 and roller 18 It will now be clear that, as the crank 12 is turned to draw the belt 11 around the rolls 8, 7 and 17, the stirrup 1A and cloth 13 will be drawn between the roll 8 and roller 18, so that whatever surplus'liquid may be contained in the cloth will be effectively expressed therefrom. It will be readily understood that the mop, due to the thickness of the cloth and contained water, will tend to separatethe rolls 8 and 18, such separation being resisted on account of the engagement of the roller 17 with the belt, the

wringing pressure on the mop thus increasing with an increase in the thickness of the member for the mop-cloth 14. lVhen the mop is in use, the cloth is normally positioned between the roll 8 and end 5, and a portion of the end of the cloth is'then positioned under the end 5 and doubled back between the bearing end 5 and the surface to be cleaned. In this manner the pressure exerted by the operator is communicated through the frame end and does not affect the mop wringing and positioningmechanisn. Furthermore, the member 5, when it has no cloth between it and the surface to be cleaned, is adapted for use as a scraper to loosen dirt adhering to the said surface.

The mop-cloth 18 may be of any desired material or form, and if of continuousbelt form may be readily placed about the stirrup member 15 by detaching one of the members 14 therefrom. It will thus be evident that the device of my invention remains assembled during all operations including that of securing the mop-cloth therein. The

stirrup bar 15 may be formed to mechanical- .ly grip the mop-cloth, or the cloth may be merely looped about it.

I claim:

l. A mop comprising a rectangular frame, a pair of rolls mounted in spaced parallel relation in said frame, an endless belt passing around said rolls, a mopping cloth secured adjacent one end to said belt and adapted to move therewith over said rolls, and means actuated by said belt adapted to resiliently press against said cloth as it moves over one of said rolls.

2. A mop comprising a rectangular frame, a pair of rolls rotatably mounted in spaced parallel relation inside said frame, an endless belt passing around said rolls, a mopcloth attached adjacent one end to said belt and adapted to move therewith over said rolls, a pressure roll cooperating with one of said first rolls and arranged to engage said cloth, means for rotating one of sald first rolls, and means associated with said oelp for imparting pressure to said pressure rol 3.
